Mark hasn't posted since May 12, but he clearly knows about iHub. Seems likely Mark is skimming this board, thus tuned to the ambient anxiety level.
Also, from your (AdultProdigy) assertions that the IP is compelling, I'm guessing Mark told you about it when you met at Parkview? If so, that's fine as long as you don't trade on the info. But if the IP truly is solid, the delay does suggest conscious stalling. Why else would Mark wait, especially when the stock is primed for a springboard higher, vis buying frenzy last week?
Personally, I'm not concerned. If the price falls on stalling, we accum more and wait a bit longer.
99.99% of all pinks are scams. Best to assume the other 0.01% are as well.
